The Temporal Layer
A current score tells you where the model stands today. Its history helps you see what changed, while lifecycle suggestions and staleness flags point to records worth reviewing.

- What a score’s history adds to the readingThe same score can reflect different histories. Understand the four trend readings and what score movement adds to a single snapshot.
- When you have grown into a different kind of firmSee how Architecture flags signs of a later lifecycle stage, the responses available and why the firm decides whether to change its stage.
- When your declared configuration stops describing your fundWhat a staleness flag detects, the two conditions that raise one, and why it says nothing about the validity of a score or the quality of a firm.
How to read this layer
The Temporal Layer produces no new scores of its own. It records each score the model produces, marks whether it is improving, stable, or declining over a recent window, surfaces a suggestion when a firm has accumulated enough structural change to warrant a different lifecycle stage, and flags a configuration that has stopped being maintained while the fund has kept deploying. It observes and records, which is a smaller job than the three engines do and a different kind of job.
Direction adds context, but it does not explain the cause. A score can change because inputs were corrected, investments accumulated or a stage changed. Use the history to identify what moved before calling it improvement or deterioration in the firm.
Each snapshot stores the lifecycle classification in force when it was taken. That detail matters more than it sounds: because some readings depend on lifecycle stage, a comparison across a transition would otherwise be comparing scores computed against different expectations. A fund whose configuration is too incomplete to score still gets a row, recorded as not computable rather than omitted, so the timeline shows when the fund was set up rather than beginning abruptly at the first complete configuration.
These pages are reference material for a reader already looking at a trend arrow, a transition prompt, or a staleness flag and wanting to know what it means.
